The atoms which make up the ion are covalently bonded to one another. 19) It is possible for a compound to possess both ionic and covalent bonding. a. If one of the ions is polyatomic then there will be covalent bonding within it.
the answer is D) The air in the aquarium is saturated
none of the other answers were realistic AND I took this before so I know the right answer.
Answer:
O pH is a measure of the concentration of H+ ions in a solution of an acid or base. The pH plots
the concentration of solutions in a range from 0-14.
Explanation:
pH is a measure of how acidic/basic water is. The range goes from 0 to 14, with 7 being neutral.
The current flowing through the lamp is 1.833A
<h3>What is current?</h3>
The current is the stream of charges which flow inside the conductors when connected across the end of voltage.
From the Ohm's law, V =IR
Here, R is the proportionality constant called resistance of the resistor
A lamp with a resistance of 60 Ohms is plugged into a 110-Volt household circuit.
I = V/R
Put the values, we get
I = 110/60
I = 1.833A
Thus, the current flowing through the lamp is 1.833A

Answer:
Explanation:
initial angular velocity, ωo = 0
angular acceleration = α
time = t
let the angular velocity after time t is ω.
Use first equation of motion for rotational motion
ω = o + α t
ω = αt
The angular momentum is given by
Angular momentum = moment of inertia x angular velocity
L = I x ω
L = I x αt
L = I α t
